The sentencing for Treveno Campbell, 25, included 25 years for the murder, eight years for the attempted murder of a second police officer, six years for employing a firearm in the commission of a dangerous felony and one year for felony drug possession with intent to sell.
Those sentences are to be served consecutively, including 31 years with no parole.
Criminal Court Judge James Beasley Jr. also gave Campbell concurrent sentences of 11 months and 29 days for each of three counts of reckless endangerment.
The shooting occurred Dec. 14, 2012, when members of the Memphis Police Department’s Organized Crime Unit executed a search warrant for drugs at 1062 Mendenhall Cove in the Berclair area of northeast Memphis.
Upon entering the residence and while placing one suspect in custody, Campbell fired shots from a bedroom, striking and killing Officer Lang. Another OCU officer, William Vrooman, was shot and wounded.
Officers returned fire, wounding Campbell, who recovered from his injuries.
The case was handled by DA Admin. Asst. Reginald Henderson and by Asst. Dist. Atty. Alanda Dwyer, chief prosecutor of the DA’s Special Prosecution Unit which seeks maximum punishment for repeat felony offenders.
